For ultra-fidelity DACs.

Ifi Audio Gemini3.0
Generic USB cables affect your music because their wiring is compacted. This causes signal and sound distortion.

The Gemini3.0 makes every other USB cable obsolete.

Go with the flow.

By carrying the audio signal and power in two separate cables, the dual-headed Gemini3.0 protects the audio signal from interference.

This produces supersonic-speed transfer which allows the best sound quality to flow right on through into your system.

It is ideally suited to ultra-fidelity DACs that cost upwards of US$10,000. Any less would be overkill.

Ifi Audio Gemini3.0

Supersonic sound.

The Gemini3.0 will change the way you listen to music on your home system.

We recommend coupling it with the iFi iGalvanic3.0 or micro USB3.0 for the ultimate supersonic sound experience.

The tech spec.

The Gemini3.0 has:

  • USB3.0 For supersonic audio speed
  • RF3 Custom Noise Silencers For effective silencing

Say goodbye to jittery audio and hello to a faster, smoother audio experience.

Super speed. The USB3.0’s ultra-speed bandwidth of 5.0Gbps offers an incredibly wide bandwidth, ten times that of USB2.0’s 480Mbps.

As with the original Gemini cable, in the Gemini3.0 the power cable is heavier gauge and audio has more cores.

Furthermore, signal and ground have their own respective geometry for optimal conductivity.

With generic mass-produced USB cables, the data and power cables are normally packed together. This means that they do not conduct as well as they should and they are not sufficiently shielded from each other. This has a negative impact on USB signal integrity and degrades sound quality.

Our quadruple shielding fully separates and protects the delicate USB data signal from the power. This protects the cable from RFI and EMI noise to provide the cleanest transfer medium possible.

Most USB cables use moulded plastic covered connections that do not shield the high frequencies present in the USB data link. Noise radiates out. Durability is compromised as few manufacturers make their own final connectors.

Our FINAL USB connectors provide impeccable end-to-end RF shielding, being machined entirely from solid, aircraft-grade aluminium.

Plus gold-plated connections make for years of steadfast service.

Most standard USB cables do not address RF issues and are fitted with filters that work over too narrow a range and are only fitted at the ends of the cables, leaving the length of the cable to act as an antennae.

iFi’s three custom-made metal oxide ceramic filters have a different effective range to broaden the range over which RF noise is silenced. The middle silencer is adjustable and can be moved along the whole length of the cable. This then “detunes” the antennae formed by the cable. The other two silencers should be kept as close to each respective end as possible.

Believe it or not, I’ve never seriously tried different USB cables. It wasn’t a topic I was interested in. Sure, I saw and tried some of them, but I’ve never critically compared them. They were just random cables that I’ve come accross when I was trying out a friend’s audio rig.

When iFi Audio offered me their new USB cables, the Gemini & Mercury I was intrigued but I was also skeptical about the topic. I have many fellow audiophiles who claim that USB cables make a difference, yet some others claim it’s a placebo effect. I don’t think this argument will ever end, and I personally will stay away from it in terms of technical subjects. When I try and test any audiophile product, I trust my ears only, and I again did so for this article…

Bought iFi’s Gemini3.0 to sort out my signal problems for my DACs. It has definitely done the job, the cable itself is very sturdy and very good quality.

I never thought about splitting the power and data before and after trying this I wouldn’t do it any other way, it’s cleaned up the audio by eliminating interference from the power lines. I am very impressed.

Overview of iFi Audio accessories and filters – does filtering matter?

This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life…

Gemini3.0 – A significant upgrade from the previous Gemini

This is an audio cable…not a printer cable. Good news, I suppose, since it’s more expensive than most printers! But what makes an audio USB cable different from a printer cable? It’s a fair question to ask before spending this kind of money.

The USB specification states, “To achieve reliable signaling at this rate, the cable is terminat”.
